About

Mon, 01 Jan 0001 00:00:00 +0000

I’m Jacob Schoenberg, co-founder and Chief Growth Officer of QWNTL Labs in San Francisco. I own growth: the market side of a research lab whose subject is agent durability, meaning whether an AI agent’s behavior holds up across days and weeks of work rather than a single task.

I’m not an engineer, and I don’t pretend to be one. My seat is in front of buyers, builders, and design partners every week, so what I bring is problem fluency and a field report you can’t get from a paper: what actually breaks when agents run long, what it costs, and how the people running them talk about it.

Send me a DM on X: @jschoen_deroolo. That’s the inbox I actually read.

LinkedIn works too, more slowly. No email, on purpose.
